In their 4th film Cheech and Chong manage to offer enough familiarity to make the film pure for fans. Simultaneously, the film offers enough new material to make this one enjoyable. The movie is a time capsule for the hardships of the early 80's. A lot of the humor would be impossible to do in today's politically correct environment, but are still funny nonetheless. These guys were good at physical a s verbal comedy and this one showcases both. This was not as good as Up in Smoke, but still really good. The guys play multiple roles in this one and they are funny. The supporting cast is great in backing them up.
